If one cannot complete the fixed number of rounds he is assigned, he should be considered to be in a diseased condition of spiritual life. Srila Haridasa Thakura is called namacarya. Of course, we cannot imitate Haridasa Thakura, but everyone must chant a prescribed number of rounds. In our Krsna consciousness movement we have fixed sixteen rounds as the minimum so that the Westerners will not feel burdened. These sixteen rounds must be chanted, and chanted loudly, so that one can hear himself and others.
